Putting a Price Tag on Bugs!

Florian Wartenberg and his team at Vestas are constantly seeking solutions to test their complex software for wind turbine more efficiently and effectively. This drive is crucial, as any excessive downtime due to software errors—or any other reason—results in penalties based on the extent of the downtimes and the loss of energy!

Florian found a solution in Teamscale’s Test Gap Analysis, which allows him to identify risky untested changes and avoid errors early on. But how could he convince management to invest in it? While testing costs are easy to quantify, the benefits are harder to express in monetary terms—the metric decision-makers care about. Thanks to the penalties, it was possible to calculate the cost of individual critical software errors and demonstrate how the Test Gap Analysis could have helped prevent them early.

In the talk, Florian Wartenberg and Fabian Streitel (head of the "Test Intelligence" team at CQSE) discuss how they jointly created an estimate of the monetary benefits of the Test Gap Analysis and what results they were able to draw from one year in practice to convince the management.
